Fertilizer spill in Mt. Pleasant prompts DNR investigation

MT. PLEASANT — The Iowa Department of Natural Resources (DNR) is investigating a fertilizer spill in Mt. Pleasant that took place Monday.

A Liqui-Grow truck rolled over near the interchange of Highway 34 and 218 around noon on April 6, causing it to spill its 2,400-gallon load as well as diesel fuel into a nearby road ditch.

The DNR states Liqui-Grow staff were able to recover 400 gallons of fertilizer. The remaining fertilizer reached an unnamed tributary of Heather Branch. Currently, Liqui-Grow’s staff has dammed the creek using sandbags and is making efforts to prevent downstream contamination by pumping up the remaining high nitrogen fertilizer.

The DNR states they were also on-site on Tuesday and Wednesday to offer technical advice and test water samples. Tests shows ammonia levels are high at the spill site but there are no signs of fish kill, according to a news release from the DNR. The department added they will continue to monitor the situation and “will consider appropriate enforcement action.”
